mechanical fuel pump question

Since the stock fuel line is 5/15...any "Stock" pump inlet is going to be 5 /16...

Going to need an aftermarket Carter or Holley pump to get the 3/8 inlet.

Carter M6902 sold by Mancini Racing only....
Yep you will have to buy an after market pump I have a holley and you put the fittings into it so you can have a nipple or like I did I used AN fittings..
